我正在申请并遇到问题
我为谷歌地图制作了单独的应用程序，它工作得很完美，我制作了第二个应用程序，其中我有listview，通过点击listview中的项目，另一个活动开始，其中打开带有不同标记的谷歌地图。
所以我设法在点击listview中的单独对象后运行另一个活动，所以我修改了对象.xml和.java文件的原理与我在谷歌地图应用程序中所做的相同，但不知何故它不起作用。
Main_Activity
package com.example.e_idem;
import android.os.Bundle;
import android.app.AlertDialog;
import android.app.ListActivity;
import android.content.DialogInterface;
import android.content.Intent;
import android.view.Gravity;
import android.view.View;
import android.widget.ArrayAdapter;
import android.widget.ListView;
import android.widget.TextView;
import android.widget.Toast;
public class MainActivity extends ListActivity {
String [] usluga = {
"Frizerski salon",
"Kafić",
"Vodoinstalater",
"Bravar",
"Ljekarna",
"Pekara",
"Autoservis",
"Dućan",
"Knjižnica",
"Papirnica",
"Željezara",
"Smartshop",
"Servis bicikla"
};
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
AlertDialog.Builder builder = new AlertDialog.Builder(this);
builder.setMessage("Odaberite uslugu koju tražite.")
.setCancelable(false)
.setPositiveButton("OK", new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int id) {
}
});
AlertDialog alert = builder.create();
alert.show();
TextView messageView = (TextView)alert.findViewById(android.R.id.message);
messageView.setGravity(Gravity.CENTER);
setListAdapter(new ArrayAdapter<String>(this, android.R.layout.simple_list_item_1, usluga));
}
public void onListItemClick(ListView parent, View view, int position,long id)
{
Toast.makeText(this, "Odabrali ste uslugu : "+usluga[position], Toast.LENGTH_LONG).show();
switch( position )
{
case 0: Intent activity_frizerski_salon = new Intent(this, FrizerskiSalon.class);
startActivity(activity_frizerski_salon);
break;
case 1: Intent activity_kafic = new Intent(this, Kafic.class);
startActivity(activity_kafic);
break;
case 2: Intent activity_vodoinstalater= new Intent(this, Vodoinstalater.class);
startActivity(activity_vodoinstalater);
break;
}
}
}
我在Main_Activity中调用的活动，用于点击listview中的对象
package com.example.e_idem;
import com.google.android.gms.maps.*;
import com.google.android.gms.maps.model.*;
import android.app.Activity;
import android.app.ListActivity;
import android.os.Bundle;
public class FrizerskiSalon extends Activity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_frizerski_salon);
// Get a handle to the Map Fragment
GoogleMap map = ((MapFragment) getFragmentManager()
.findFragmentById(R.id.fmap)).getMap();
LatLng vz = new LatLng(46.305746, 16.336606);
map.setMyLocationEnabled(true);
map.moveCamera(CameraUpdateFactory.newLatLngZoom(vz, 13));
map.addMarker(new MarkerOptions()
.title("Varaždin")
.snippet("Barokni grad")
.position(vz));
map.addMarker(new MarkerOptions()
.icon(BitmapDescriptorFactory.fromResource(R.drawable.flag_red))
.anchor(0.0f, 1.0f) // Anchors the marker on the bottom left
.position(new LatLng(46.300274, 16.330769)));
map.addMarker(new MarkerOptions()
.icon(BitmapDescriptorFactory.fromResource(R.drawable.flag_red))
.anchor(0.0f, 1.0f) // Anchors the marker on the bottom left
.position(new LatLng(46.306274, 16.300769)));
map.addMarker(new MarkerOptions()
.icon(BitmapDescriptorFactory.fromResource(R.drawable.flag_red))
.anchor(0.0f, 1.0f) // Anchors the marker on the bottom left
.position(new LatLng(46.306974, 16.303169)));
map.addMarker(new MarkerOptions()
.icon(BitmapDescriptorFactory.fromResource(R.drawable.flag_red))
.anchor(0.0f, 1.0f) // Anchors the marker on the bottom left
.position(new LatLng(46.302874, 16.400710)));
}
}

您的清单文件中需要2个元数据条目：
1）地图密钥
<meta-data
android:name="com.google.android.maps.v2.API_KEY"
android:value="AIzaSyCKxxxxxxxxxxxxxxxxxxVfSY_9zxmU"/>
2）谷歌播放服务版
<meta-data
android:name="com.google.android.gms.version"
android:value="@integer/google_play_services_version" />
